Under the Hood: Mature devices get Rolly rocking
Teardown 5/13/2008 Post a comment
The Sony Rolly, shown at the Consumer Electronics Show in January, is a "dancing" MP3 player: When songs are loaded or streamed via Bluetooth, the Rolly can roll around and flap its speaker coverings in time with the music. The speaker flaps can also muffle the sound and give it a bit more flare when noise is channeled through one side or the other.

Statistical Range Analysis in RF Systems: the "Range Fallacy"
Design How-To 5/5/2008 2 comments
You read every paper you could get your hands on to do with propagation and path loss at the frequency you're using, and you carefully included all the known (and measured) losses, antenna gains, power outputs and sensitivities in a detailed link budget. A few days later the marketing dept arrives at your office: "You said the range would be 5 meters but we tried it at that distance and we could make it fail." What has gone wrong?
60GHz: Achieving the ultimate wireless dream
Design How-To 5/5/2008 Post a comment
Using sophisticated design and fabrication techniques, research labs are getting closer to realizing 60GHz chips in silicon. When that happens, consumer price points can be met and wireless design becomes a whole new ballgame. But first, engineers must overcome five major challenges.
